It'd be nice to input some constants and some things that vary, and ktcalc outputs a table with one row per combination. The row would have avg dmg, then p(>=dmg) for dmg=1..20.
Could use UI elements where instead of a dropdown where you select one option, you get checkboxes where you can select any number of options.
Or, could go text-based route where input is something like "A=4 BS=3,4 N=3 C=4 Lethal=4..6 Rending=1 Sv=*" with unstated things going to defaults, like Def=3.
Or both. People use the UI elements to explore and can see the text equivalent, then it is easy to copy and remember that text for later.
